{mi ca'a ku pu broda} works.
{mi pu ca'a broda} works.
{mi ca'a pu broda} does not work.

The parser treats the glob {puca'a} as a single modal.

{ca'aku pu} is treated as two modals.

{ca'a pu} fails because the grammar only allows PU and CAhA to be glommed
into the same modal when they're in the order PU+CAhA

Why it does that, I don't know. I don't immediately see why it can't allow
CAhA+PU also. Assuming that someone can't figure out why in a day or two,
I'll try abusing the grammar to see if it remains LALR(1) with that
change.
